Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy and hydropower surveying, and specifically, to a surveying method for water conservancy and hydropower construction. Background Technique

[0002] Water conservancy and hydropower engineering mainly studies the basic knowledge and skills in aspects such as water resources, hydraulic structures, hydraulics and fluid dynamics, and water conservancy engineering technology. Water conservancy and hydropower engineering utilizes large and medium-sized water conservancy and hydropower hubs and their buildings, including dams, hydropower station buildings, gates, and water discharge buildings, etc., and uses the potential energy of relevant water to carry out corresponding power generation work. Among them, the planning, design, construction, management, and scientific research of these buildings in water conservancy and hydropower engineering all belong to the working objects of water conservancy and hydropower engineering. During the construction process of these large and medium-sized buildings, in order to ensure the stability of the construction of water conservancy and hydropower engineering buildings, for example, after the completion of water conservancy and hydropower engineering, the water body and the surrounding soil will interact with each other, and pollutants in the soil (such as heavy metals, organic matters, etc.) may seep into the water body, affecting water quality. Therefore, before construction, it is necessary to conduct a survey of the soil.

[0003] Existing soil sampling equipment mainly relies on its thin-walled structure, and then uses external force to press it into the soil for sampling. After sampling, the soil often adheres tightly to the inner wall of the equipment, making it more laborious when manually pushing out the soil during subsequent separation work. Moreover, if the force is not applied properly during manual pushing, it is easy to damage the original structure of the soil sample;

[0004] In addition, when the soil sampler is pulled out of the soil, due to the influence of gravity and possible external factors such as shaking and vibration, the soil sample in the soil sampler is very easy to fall out from the bottom, resulting in a reduction in the sample volume, and further affecting the accuracy and integrity of subsequent detection and analysis. In view of this, we propose a surveying method for water conservancy and hydropower construction. Summary of the Invention

[0005] The purpose of the present invention is to provide a surveying method for water conservancy and hydropower construction to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the present invention provides a surveying method for water conservancy and hydropower construction, including the following steps:

[0007] S1. Place the surveying equipment for water conservancy and hydropower construction at the survey point:

[0008] S2. Insert the sampler into the soil by applying external pressure so that the soil fills the sampler:

[0009] S3. Then pull out the sampler from the soil by applying external force, and then separate the soil in the sampler, where:

[0010] The sampler at least comprises a bottom plate, four corners of which are fixedly connected with support columns, a plurality of support columns are slidably connected with a mounting box, a sampling cylinder for sampling is slidably connected below the mounting box, and a receiving mechanism and a driving mechanism are provided inside the sampling cylinder;

[0011] After the sampling is completed, the receiving mechanism is driven by the driving mechanism to move downward and contract. During the downward movement of the receiving mechanism, the adhesion between the soil and the inner wall of the sampling tube is broken. Moreover, when the receiving mechanism moves to the opening of the sampling tube, the driving mechanism drives the receiving mechanism to rotate from a vertical state to be parallel to the bottom of the sampling tube, so that during the process of pulling out the sampling tube, the receiving mechanism receives the bottom of the sampling tube.

[0012] The sampling tube is also provided with an auxiliary mechanism. When the receiving mechanism is reset and moved, the auxiliary mechanism guides the receiving mechanism to move and drives the receiving mechanism to elastically contract.

[0013] As a further improvement of the technical solution, the receiving mechanism at least includes a multi-section connecting plate slidably connected to the inner wall of the sampling tube, and a multi-section receiving plate is fixedly connected to the bottom of the multi-section connecting plate.

[0014] As a further improvement of the present technical solution, the driving mechanism includes at least a moving block slidably connected in the sampling tube slide groove, one side of the moving block is rotatably connected to a mounting rod, and one side of the mounting rod passes through the moving block, one side of the mounting rod passes through the moving block and is fixedly connected to a rotating rod, and the side of the rotating rod away from the moving block is fixedly connected to the multi-section connecting plate.

[0015] As a further improvement of the present technical solution, a gear is fixedly connected to the side of the mounting rod away from the rotating rod, a straight tooth plate is fixedly connected to the inner wall of the sampling tube slide groove, a sliding rod is fixedly connected to the top of the moving block, and the side of the sliding rod away from the moving block passes through the sampling tube and the mounting box in sequence and extends to the outside of the mounting box.

[0016] As a further improvement of the technical solution, a partition is fixedly connected to the inner wall of the sampling tube, and a multi-section receiving plate is arranged above the partition.

[0017] As a further improvement of the present technical solution, the auxiliary mechanism includes a pillar fixedly connected to the bottom of the partition, the outer wall of the pillar is rotatably connected to a folding rod, the multi-section supporting plate is rotatably connected to a support rod on one side close to the partition, a No. 4 return spring is fixedly connected to the bottom of the support rod, and the No. 4 return spring is fixedly connected to the folding rod on the side away from the support rod.

[0018] As a further improvement of the technical solution, a No. 2 return spring is fixedly connected between the multi-section connecting plates in pairs, and a No. 3 return spring is fixedly connected between the multi-section receiving plates in pairs.

[0019] As a further improvement of the technical solution, two sets of the sampling cylinder, the receiving mechanism, the driving mechanism and the auxiliary mechanism are provided, and the distance value between one set of the straight tooth plate, the partition plate and the auxiliary mechanism and the bottom of the sampling cylinder is greater than that of the other set.

[0020] As a further improvement of the technical solution, a bidirectional lead screw is rotatably connected inside the installation box, and one side of the bidirectional lead screw penetrates through the installation box. Two sliders are screwed on the bidirectional lead screw, and the two sliders are respectively fixedly connected to one side of the adjacent sampling cylinder.

[0021] As a further improvement of the technical solution, a first return spring is sleeved on the outer wall of multiple support columns, and the first return spring is located between the installation box and the support columns. The bottom of the sampling cylinder is serrated.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. In the survey method for water conservancy and hydropower construction, while the driving mechanism drives the multi-section receiving plate to contract, it drives the multi-section receiving plate to rotate to be parallel to the bottom of the sampling cylinder;

[0024] After sampling is completed, manually press the driving mechanism to drive the multi-section receiving plate to move downward while elastically contracting, so that a relative displacement occurs between the multi-section receiving plate and the soil, thereby breaking the adhesion state between the multi-section receiving plate and the soil, facilitating the subsequent separation of the soil from the sampling cylinder;

[0025] When the driving mechanism continues to drive the multi-section receiving plate to move towards the serrated end of the sampling cylinder, it can drive the multi-section receiving plate to rotate, so that the multi-section receiving plate rotates from the vertical state to be parallel to the bottom of the sampling cylinder, thereby receiving the lower part of the sampling cylinder, effectively preventing too much soil inside the sampling cylinder from falling out from the bottom of the sampling cylinder when the sampling cylinder is pulled out of the soil.

[0026] 2. In the survey method for water conservancy and hydropower construction, when the multi-section receiving plate rotates, it can drive the folding rod to move synchronously. The folding rod can provide support and guidance for the movement of the multi-section receiving plate. And when the driving mechanism drives the multi-section receiving plate to move back to its original position later, under the height limitation of the folding rod, the multi-section receiving plate can contract while moving upward, thus avoiding movement interference between the multi-section receiving plate and the internal parts of the sampling cylinder due to excessive length when the multi-section receiving plate returns to its original position, enabling the multi-section receiving plate to be received above the partition plate to prepare for the next work.

[0040] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figures 1-8 As shown, this embodiment provides a survey method for water conservancy and hydropower construction, comprising the following steps:

[0042] S1. Place the survey equipment for water conservancy and hydropower construction at the survey point:

[0043] S2. Insert the sampler into the soil by applying external pressure so that the soil fills the sampler:

[0044] S3, then pull the sampler out of the soil by external force, and then separate the soil in the sampler, wherein:

[0045] The sampler at least comprises a bottom plate 100, and support columns 110 are fixedly connected at four corners of the bottom plate 100, and a mounting box 120 is slidably connected to the plurality of support columns 110. The support columns 110 are provided to provide guidance for the sliding of the mounting box 120, and a sampling cylinder 130 for sampling is slidably connected below the mounting box 120. The sampling cylinder 130 is inserted into the soil so that the soil fills the sampling cylinder 130, and a receiving mechanism 200 and a driving mechanism 300 are provided inside the sampling cylinder 130;

[0046] After the sampling is completed, the receiving mechanism 200 is driven by the driving mechanism 300 to move downward and retract. During the downward movement of the receiving mechanism 200, the adhesion between the soil and the inner wall of the sampling tube 130 is broken, so that the soil can be separated from the sampling tube 130 later. Moreover, when the receiving mechanism 200 moves to the opening of the sampling tube 130, the driving mechanism 300 drives the receiving mechanism 200 to rotate from the vertical state to be parallel to the bottom of the sampling tube 130, so that during the extraction of the sampling tube 130, the receiving mechanism 200 receives the bottom of the sampling tube 130, effectively preventing the excessive falling of the soil inside the sampling tube 130.

[0047] An auxiliary mechanism 400 is also provided on the sampling tube 130. When the receiving mechanism 200 is reset and moved, the auxiliary mechanism 400 guides the receiving mechanism 200 to move while driving the receiving mechanism 200 to elastically contract, thereby avoiding movement interference between the receiving mechanism 200 and components on the bottom plate 100, so that the receiving mechanism 200 can be vertically retracted into the sampling tube 130 after being reset.

[0048] The present invention takes into account that the existing soil sampling equipment mainly relies on its thin-wall structure, and then uses external force to press it into the soil for sampling. After sampling, the soil is often tightly adhered to the inner wall of the equipment, which makes it more laborious to manually push out the soil during subsequent separation work; therefore, a receiving mechanism 200 and a driving mechanism 300 are provided. After the sampling of the sampling tube 130 is completed, the driving mechanism 300 is manually pressed to drive the receiving mechanism 200 to move downward while elastically contracting, so that a relative displacement occurs between the receiving mechanism 200 and the soil, thereby breaking the adhesion state between the receiving mechanism 200 and the soil, and facilitating the subsequent separation of the soil from the sampling tube 130;

[0049] It is also considered that when the soil sampler is pulled out of the soil, due to the effect of gravity and possible external factors such as shaking and vibration, the soil sample in the soil sampler is easy to fall from the bottom, resulting in a reduction in the sample volume, which in turn affects the accuracy and completeness of subsequent detection and analysis; therefore, when the driving mechanism 300 continues to drive the receiving mechanism 200 to move downward, it can drive the receiving mechanism 200 to rotate, so that the receiving mechanism 200 rotates from the vertical state to be parallel to the bottom of the sampling tube 130, thereby receiving the bottom of the sampling tube 130, effectively preventing the excessive soil inside the sampling tube 130 from falling out from the bottom of the sampling tube 130 when the sampling tube 130 is pulled out of the soil;

[0050] In addition, when the receiving mechanism 200 rotates, it can drive the auxiliary mechanism 400 to move synchronously, and can provide support and guidance for the movement of the receiving mechanism 200. When the subsequent driving mechanism 300 drives the receiving mechanism 200 to reset, under the restriction of the auxiliary mechanism 400, the receiving mechanism 200 can move upward and retract at the same time, thereby avoiding the movement interference between the receiving mechanism 200 and the internal parts of the sampling tube 130 due to its excessive length when the receiving mechanism 200 is reset, so that the receiving mechanism 200 can be vertically retracted into the sampling tube 130.

[0051] When the sampling tube 130 is taken out from the soil, in order to prevent the soil inside the sampling tube 130 from falling too much, Figures 2-4 As shown, the specific structure of the receiving mechanism 200 is further disclosed. The receiving mechanism 200 at least includes a multi-section connecting plate 210 slidably connected to the inner wall of the sampling tube 130, and a multi-section receiving plate 211 is fixedly connected to the bottom of the multi-section connecting plate 210;

[0052] After the sampling tube 130 has finished sampling, the driving mechanism 300 drives the multi-section connecting plate 210 to move downward, thereby driving the multi-section receiving plate 211 to move downward. During the movement and contraction of the multi-section connecting plate 210 and the multi-section receiving plate 211, the adhesion between the soil and the multi-section connecting plate 210 and the multi-section receiving plate 211 can be broken, so that the soil can be separated from the sampling tube 130 later.

[0053] When the multi-section connecting plate 210 and the multi-section receiving plate 211 continue to move downward, the driving mechanism 300 can drive the multi-section connecting plate 210 to rotate, thereby driving the multi-section receiving plate 211 to rotate, so as to prevent excessive soil inside the sampling tube 130 from falling when the sampling tube 130 is taken out.

[0054] In order to drive the multi-section connecting plate 210 to move, Figures 3-4As shown, the specific structure of the driving mechanism 300 is further disclosed. The driving mechanism 300 at least includes a moving block 310 slidably connected in the chute of the sampling cylinder 130. One side of the moving block 310 is rotatably connected with a mounting rod 311, and one side of the mounting rod 311 penetrates through the moving block 310. A rotating rod 312 is fixedly connected to the side of the mounting rod 311 penetrating through the moving block 310, and the side of the rotating rod 312 away from the moving block 310 is fixedly connected with a multi-section connecting plate 210. When the moving block 310 moves, it drives the rotating rod 312 to move, thereby driving the multi-section connecting plate 210 to move.

[0055] In order to drive the multi-section connecting plate 210 to rotate, as Figure 3 and Figure 7 shown, a gear 313 is fixedly connected to the side of the mounting rod 311 away from the rotating rod 312. A straight tooth plate 314 is fixedly connected to the inner wall of the chute of the sampling cylinder 130. A sliding rod 315 is fixedly connected to the top of the moving block 310, and the side of the sliding rod 315 away from the moving block 310 sequentially penetrates through the sampling cylinder 130 and the mounting box 120 and extends to the outside of the mounting box 120. Manually pressing down the sliding rod 315 drives the moving block 310 to move downward, thereby driving the mounting rod 311 to move downward, and further driving the rotating rod 312 to move downward. When the mounting rod 311 continues to move downward, the gear 313 meshes with the straight tooth plate 314, driving the mounting rod 311 to rotate, thereby driving the rotating rod 312 to rotate, and further driving the multi-section connecting plate 210 to rotate.

[0056] When the multi-section connecting plate 210 and the multi-section receiving plate 211 move downward, in order to prevent the multi-section receiving plate 211 from being inserted into the soil at the opening of the sampling cylinder 130, as Figure 3 shown, a partition plate 133 is fixedly connected to the inner wall of the sampling cylinder 130, and the multi-section receiving plate 211 is arranged above the partition plate 133. When the multi-section connecting plate 210 and the multi-section receiving plate 211 move downward, an extrusion occurs between the multi-section receiving plate 211 and the partition plate 133. When the multi-section connecting plate 210 continues to move downward, it drives the multi-section connecting plate 210 and the multi-section receiving plate 211 to contract.

[0057] When the multi-section receiving plate 211 needs to move in a reset manner, the multi-section receiving plate 211 needs to contract first to avoid movement interference between the multi-section receiving plate 211 and the partition plate 133 during reset due to the excessive length of the multi-section receiving plate 211, resulting in the multi-section receiving plate 211 not being able to be received above the partition plate 133, as Figures 5-8As shown, the specific structure of the auxiliary mechanism 400 is further disclosed. The auxiliary mechanism 400 includes a support column 410 fixedly connected below the partition plate 133. A folding rod 411 is rotatably connected to the outer wall of the support column 410. One side of the multi-segment receiving plate 211 close to the partition plate 133 is rotatably connected to a support rod 412. A fourth return spring 413 is fixedly connected to the bottom of the support rod 412, and the side of the fourth return spring 413 away from the support rod 412 is fixedly connected to the folding rod 411. When the multi-segment receiving plate 211 is reset later, when the multi-segment receiving plate 211 moves upward and rotates for reset, the folding rod 411 can limit the multi-segment receiving plate 211 from tilting and protruding out of the sampling cylinder 130, so that the multi-segment receiving plate 211 can shrink while moving upward, thus avoiding movement interference between the multi-segment receiving plate 211 and the partition plate 133 when the multi-segment receiving plate 211 is too long during reset, enabling the multi-segment receiving plate 211 to be retracted above the partition plate 133. The fourth return spring 413 is provided to assist the folding rod 411 in moving.

[0058] When the multi-segment connecting plate 210 and the multi-segment receiving plate 211 are squeezed, they can contract, and when not squeezed, they can move in reset, as Figure 4 shown. A second return spring 212 is fixedly connected between two adjacent plates of the multi-segment connecting plate 210. When the multi-segment connecting plate 210 is squeezed, the second return spring 212 between two adjacent plates of the multi-segment connecting plate 210 is compressed and deformed. Subsequently, when the multi-segment connecting plate 210 is not compressed, under the force of the second return spring 212 restoring deformation, it can drive the two adjacent plates of the multi-segment connecting plate 210 to move in reset. A third return spring 213 is fixedly connected between two adjacent plates of the multi-segment receiving plate 211. When the multi-segment receiving plate 211 is squeezed, the third return spring 213 between two adjacent plates of the multi-segment receiving plate 211 is compressed and deformed. Subsequently, when the multi-segment receiving plate 211 is not compressed, under the force of the third return spring 213 restoring deformation, it can drive the two adjacent plates of the multi-segment receiving plate 211 to move in reset.

[0059] To better separate the soil from the sampling cylinder 130, as Figure 3 shown, two sets of the sampling cylinder 130, the receiving mechanism 200, the driving mechanism 300, and the auxiliary mechanism 400 are provided. The distance between one set of the straight-tooth plate 314, the partition plate 133, and the auxiliary mechanism 400 and the bottom of the sampling cylinder 130 is greater than that of the other set. When pressing the sliding rod 315, first press the one with a greater distance from the bottom of the sampling cylinder 130, and then press the other sliding rod 315, so that the multi-segment receiving plate 211 farther from the bottom of the sampling cylinder 130 rotates first, so that the two multi-segment receiving plates 211 are arranged in an alternating parallel manner after rotation, so that the two multi-segment receiving plates 211 can support each other, making the multi-segment receiving plate 211 more stable when receiving the bottom of the sampling cylinder 130.

[0060] To further better remove the soil from the sampling cylinder 130, as Figure 2 shown, a bidirectional lead screw 131 is rotatably connected inside the installation box 120, and one side of the bidirectional lead screw 131 penetrates through the installation box 120. Two sliders 132 are screwed on the bidirectional lead screw 131, and the two sliders 132 are respectively fixedly connected to one side of the adjacent sampling cylinder 130. When the bidirectional lead screw 131 is manually rotated, the bidirectional lead screw 131 is driven to rotate, thereby driving the slider 132 to linearly move on the bidirectional lead screw 131, and then driving the sampling cylinder 130 to move. When the sampling cylinder 130 needs to sample, the two sampling cylinders 130 move closer to each other, so that the two sampling cylinders 130 are in contact with each other. When the sampling of the sampling cylinder 130 is completed, the sampling cylinders 130 move away from each other, which is convenient for removing the soil inside the sampling cylinder 130. In addition, the separation of the two sampling cylinders 130 is also convenient for subsequent cleaning work inside the sampling cylinder 130.

[0061] In order for the sampling cylinder 130 to better break through the soil and insert into the soil, as Figure 2 shown, a first return spring 121 is sleeved on the outer wall of multiple support columns 110, and the first return spring 121 is located between the installation box 120 and the support column 110. When the device is not in use, under the action of the first return spring 121, the installation box 120 can be driven back to the initial position. The bottom of the sampling cylinder 130 is serrated. When inserting into the soil, the tips of the serrations can break through the soil first and cut the soil into small pieces. Compared with the sampling cylinder 130 with a smooth bottom, it reduces the contact area with the soil and reduces the difficulty of inserting the sampling cylinder 130 into the soil, making the entire sampling operation proceed more smoothly.

[0062] Working principle: When soil sampling is required, first manually press down the installation box 120. When driving the installation box 120 to move downward, in cooperation with the bidirectional lead screw 131 and the slider 132, the sampling cylinder 130 is driven to move downward, and the sampling cylinder 130 inserts into the soil for sampling work;

[0063] After the sampling is completed, one of the slide bars 315 is manually pressed downward to drive the moving block 310 to move downward, thereby driving the mounting bar 311 to move downward, and then driving the rotating bar 312 to move downward. When the rotating bar 312 moves downward, the multi-segment connecting plate 210 is driven downward, thereby driving the multi-segment receiving plate 211 to move downward. Under the limitation of the spacing value between the inner wall of the sampling tube 130 and the partition 133, the multi-segment connecting plate 210 and the multi-segment receiving plate 211 move downward at the same time. The multi-section connecting plate 210 and the multi-section receiving plate 211 move, and the original part of the soil is in close contact with the multi-section connecting plate 210 and the multi-section receiving plate 211. During the movement and contraction of the multi-section connecting plate 210 and the multi-section receiving plate 211, the adhesion between the soil and the multi-section connecting plate 210 and the multi-section receiving plate 211 can be broken, so that the soil can be separated from the sampling tube 130 later.

[0064] When the mounting rod 311 moves downward, it meshes with the spur plate 314, thereby driving the mounting rod 311 to rotate, and then driving the rotating rod 312 to rotate. The rotating rod 312 rotates and drives the multi-section connecting plate 210 and the multi-section receiving plate 211 to rotate. At this time, there is no partition 133 to restrict the multi-section receiving plate 211. Therefore, under the elastic force of the second return spring 212 and the third return spring 213, the multi-section connecting plate 210 and the multi-section receiving plate 211 can be driven to extend, so that the bottom of the sampling tube 130 can be received, so as to prevent the soil inside the sampling tube 130 from falling out when the sampling tube 130 is taken out;

[0065] When the multi-segment receiving plate 211 rotates, the elastic movement of the multi-segment receiving plate 211 drives the support rod 412 to move, thereby pulling the folding rod 411 to move. When the multi-segment receiving plate 211 is subsequently reset, the multi-segment receiving plate 211 moves upward and rotates to reset. The folding rod 411 can limit the multi-segment receiving plate 211 from extending obliquely to the outside of the sampling tube 130, so that the multi-segment receiving plate 211 can move downward and retract at the same time, thereby avoiding the multi-segment receiving plate 211 being too long and causing movement interference with the partition 133 when the multi-segment receiving plate 211 is reset.

[0066] The above shows and describes the basic principles, main features and advantages of the present invention.
